倾斜煤层开采对底板突水影响的数值模拟

为了研究倾斜煤层开采条件下的突水规律,在考虑原岩应力、地质构造、地下水、采动影响等因素基础上,从应力场和渗流场共同作用的角度出发,研究含底板岩体在内的采场岩体系统的变形与破坏。研究结果表明,随着工作面的推进,底板岩层的破坏深度和范围加速增加。研究结论将数值模拟结果与工程实际进行比较分析,为寻求安全、经济的开采方法提供了理论依据。

Simulation study on effect of inclined strata coal mine on floor water invasion

To research the water invasion regularity in mining inclined coal seam,on the basic of considering rock stress,geological structure,groundwater,mining influence and so on,deformation and failure of stopes rocks bodysystem(including the disturbance band) are studied from the perspective of the combined action of stress field and seepage field.The results show that the failure depth and range of the floor strata increase with wordface advancing.The numerical simulation results are analyzed comaratively with e...
